#1
Marisa G Franco, Karen M O'Brien
OBJECTIVES: Racial identity invalidation, others' denial of an individual's racial identity, is a salient racial stressor with harmful effects on the mental health and well-being of Multiracial individuals. The purpose of this study was to create a psychometrically sound measure to assess racial identity invalidation for use with Multiracial individuals (N = 497). METHOD: The present sample was mostly female (75%) with a mean age of 26.52 years (SD = 9.60). The most common racial backgrounds represented were Asian/White (33...

Life-history theory predicts trade-offs between reproductive and survival traits such that different strategies or environmental constraints may yield comparable lifetime reproductive success among conspecifics. Food availability is one of the most important environmental factors shaping developmental processes. It notably affects key life-history components such as reproduction and survival prospect. We investigated whether food resource availability could also operate as an ultimate driver of life-history strategy variation between species...

BACKGROUND: A substantial period of life after reproduction ends, known as postreproductive lifespan (PRLS), is at odds with classical life history theory and its causes and mechanisms have puzzled evolutionary biologists for decades. Prolonged PRLS has been confirmed in only two non-human mammals, both odontocete cetaceans in the family Delphinidae. We investigate the evidence for PRLS in a third species, the false killer whale, Pseudorca crassidens, using a quantitative measure of PRLS and morphological evidence from reproductive tissues...

Lisa D Pearce, Shannon N Davis
This paper examines intermediary processes explaining how religious socialization and involvement early in life are related to the timing of first births for women in the United States. The theory of conjunctural action forms the basis for hypotheses for how religious schema and materials operate to influence birth timing. Using the NLSY79 data and event history methods, the study finds evidence for expected family size, work-family gender ideology, educational attainment and enrollment, cohabitation, and age at marriage as mediators of associations between early life religious exposure (affiliation and attendance) and the timing of nonmaritally and maritally conceived first births...

Through the case study of the school of gunners created in Seville in 1576, this article aims to shed light on the emergence of teaching practices which were not only essential to the development of seaborne empires but also allow us to question the relationship between technology and science in the late Renaissance. The Seville school of gunners was established by the Spanish monarchy in the last quarter of the sixteenth century with the purpose of providing the Carrera de Indias-the transatlantic fleets-with technicians capable of using cannons...

#6
Patricia M Gough, Emily L Connally, Peter Howell, David Ward, Jennifer Chesters, Kate E Watkins
PURPOSE: Previous studies have reported that the planum temporale - a language-related structure that normally shows a leftward asymmetry - had reduced asymmetry in people who stutter (PWS) and reversed asymmetry in those with severe stuttering. These findings are consistent with the theory that altered language lateralization may be a cause or consequence of stuttering. Here, we re-examined these findings in a larger sample of PWS. METHODS: We evaluated planum temporale asymmetry in structural MRI scans obtained from 67 PWS and 63 age-matched controls using: 1) manual measurements of the surface area; 2) voxel-based morphometry to automatically calculate grey matter density...

BACKGROUND: Biofilm has been suggested as a cause of disinfection failures in flexible endoscopes where no lapses in the decontamination procedure can be identified. To test this theory, the activity of peracetic acid (PAA), one of the commonly used disinfectants in the reprocessing of flexible endoscopes, was evaluated against both planktonic and sessile communities of Pseudomonas aeruginosa. AIM: To investigate the ability of P. aeruginosa biofilm to survive high level PAA disinfection...

BACKGROUND: Recent exercise guidelines for people with multiple sclerosis (MS) recommend a minimum of 30 min moderate intensity aerobic exercise and resistance exercise twice per week. This trial compared the secondary outcomes of a combined 10-week guideline based intervention and a Social Cognitive Theory (SCT) education programme with the same exercise intervention involving an attention control education. METHODS: Physically inactive people with MS, scoring 0-3 on Patient Determined Disease Steps Scale, with no MS relapse or change in MS medication, were randomised to 10-week exercise plus SCT education or exercise plus attention control education conditions...

Parent-youth and peer relationship inventories based on attachment theory measure communication, trust, and alienation, yet sibling relationships have been overlooked. We developed the Sibling Attachment Inventory and evaluated its psychometric properties in a sample of 172 youth ages 10-14 years. We adapted the 25-item Sibling Attachment Inventory from the Inventory of Parent and Peer Attachment-Revised peer measure. Items loaded onto three factors, identified as communication, trust, and alienation, α = 0...

INTRODUCTION: Stigma and discrimination contribute to elevated depression risks among sexual minority women (SMW) and gender minority (GM) people who identify as lesbian, bisexual, or queer. Syndemics theory posits that adverse psychosocial outcomes cluster to negatively impact health and mental health outcomes among sexual minorities. We tested whether a syndemic condition composed of low social support, low self-rated health, low self-esteem, and economic insecurity mediated the relationship between sexual stigma and depressive symptoms among SMW/GM...

Ecosystem development theory predicts that successional turnover in community composition can influence ecosystem functioning. However, tests of this theory in natural systems are made difficult by a lack of replicable and tractable model systems. Using the microbial digestive associates of a carnivorous pitcher plant, I tested hypotheses linking host age-driven microbial community development to host functioning. Monitoring the yearlong development of independent microbial digestive communities in two pitcher plant populations revealed a number of trends in community succession matching theoretical predictions...

AIM: The aim of this study was to test the mediating role of the satisfaction of dental students' basic psychological needs of autonomy, competence and relatedness on the association between learning climate, feedback and student motivation. The latter was based on the self-determination theory's concepts of differentiation of autonomous motivation, controlled motivation and amotivation. METHODS: A cross-sectional correlational study was conducted where 924 students completed self-reported questionnaires measuring motivation, perception of the learning climate, feedback and basic psychological needs satisfaction...

For drug development in neurodegenerative diseases such as Alzheimer's disease, it is important to understand which cognitive domains carry most information on earliest signs of cognitive decline, and which subject characteristics are associated with a faster decline. A longitudinal Item Response Theory (IRT) model was developed for the Basel Study of the Elderly, in which the Consortium to Establish a Registry for Alzheimer's Disease - Neuropsychological Assessment Battery (with additions) and the California Verbal Learning Test were measured on 1750 elderly subjects for up to 13...

This study focused on parents' motivations to transmit values to their adolescent children. According to Self-Determination Theory, controlled motivations (i.e., external and introjected)-which refer to doing something because it leads to approval or rewards-and autonomous motivations (i.e., identified and integrated)-which refer to doing something because it is perceived as inherently worthy-were examined. 325 Italian parental couples, with one child aged between 14 and 18 years, filled out a self-report questionnaire...

In the psychological literature, there is growing evidence that parental support of children's volitional functioning is one of the most prominent protective factors during adolescence and the transition to adulthood. According to the Self-Determination Theory, children cope best with developmental tasks when they acquire a sense of self-governance and self-endorsed functioning. In the field of adoption research, however, the parental promotion of volitional functioning (PVF) and its relation to the adopted child's development are still underinvestigated...

#17
Jessica L Borelli, Kajung Hong, Hannah F Rasmussen, Patricia A Smiley
Theorists argue that parental reflective functioning (PRF) is activated in response to emotions, potentially supporting parenting sensitivity even when arousal is high. That is, when parents become emotionally reactive when interacting with their children, those who can use PRF to understand their children's mental states should be able to parent sensitively, which, in turn, should promote children's ability to understand their own mental states. We test this theory by examining whether, in the face of physiological reactivity, mothers' PRF inhibits one form of parenting insensitivity, overcontrol (OC), and whether this process in turn predicts children's RF...

This study is part of the Promoting Aging Migrants' Capabilities programme that applied person-centred group meetings and one individual home visit to prolong independence in daily activities among people ≥70 years who had migrated to Sweden from Finland or the Western Balkan region. With the purpose to understand programme outcomes, the study aimed to explore the participants' everyday experiences of using health-promoting messages exchanged during the programme. Using a grounded theory approach, 12 persons aged 70-83 years were interviewed six months to one year after their participation in the programme...

When fixating on a stationary object, the power of the eye's lens fluctuates. Studies have suggested that changes in these so-called microfluctuations in accommodation may be a factor in the onset and progression of short-sightedness. Like many physiological signals, the fluctuations in the power of the lens exhibit chaotic behaviour. A breakdown or reduction in chaos in physiological systems indicates stress to the system or pathology. The purpose of this study was to determine whether the chaos in fluctuations of the power of the lens changes with refractive error, i...

Hod Orkibi, Tammie Ronen
Although studies have shown that self-control skills (SCSs) are positively linked to both personal and interpersonal outcomes in adolescent students, studies on the putative mechanisms underlying this relationship are scarce. Drawing on Self-Determination Theory and previous studies, we theorized that the association between students' SCSs and their subjective well-being (SWB) in school may be mediated by students' perceived satisfaction of their basic psychological needs for competence, relatedness, and autonomy...
